So domain is the number you can use
range is the output your get from inputting the domain given
so from 2≤x≤5
since it is linear, we can be sure that we only need to test the endpoints of the domain to find the endpoints of the range
sub 2 for x
y=2(2)+1
y=4+1
y=5
sub 5 for x
y=2(5)+1
y=10+1
y=11
so range is from 5 to 11
in interval notation: [5,11]
in other notation 5≤y≤11
or
R={y|5≤y≤11}
Answer:
Graph (C)
Step-by-step explanation:
To find whether the graph\table represents a relationship or a function we have to analyze the input-output values given.
Graph A.
In this graph for every input value (x-value) there are two output values (y-values).
For x = -2, y = -2, 2
So the graph doesn't represent a function.
Graph B.
For every x value there are two y-values
For x = -5, y = -3, 3
So the graph doesn't represent a function.
Graph C.
For every input value there is a different y-value.
Therefore, graph represents a function.
Graph D.
In this graph for x = 3, y = 1, 2, 3, 4
For one value of x, there are four values of y.
Therefore, graph doesn't show the relationship.
Answer:
Lucas monthly net pay is $1758
Step-by-step explanation:
Lucas works for a salary of $2,396 per month.
His deductions include $360 of federal income tax,
$148 for Social Security,
$35 for Medicare, and
a $95 insurance premium.
Now,
2396 - 360 - 148 - 35 - 95 = 1758
Thus, Lucas monthly net pay is $1758

What is the median of the data set? <br>
{10, 15, 14, 14, 10, 10, 8, 18, 11, 12, 17, 16}

The median of a data set is the 'middle number'. You can find the median by listing the given numbers from least to greatest (left to right) and finding the middle number.
8, 10, 10, 10, 11, 12, 14, 14, 15, 16, 17, 18
Cross one out on each side before getting to your last number that should be in the middle.
The middle numbers are: 12 and 14. If it was only one number, we could already have the answer, but since it is two numbers in the middle, we need to add them up and divide by 2.
12 + 14 = 26
26 ÷ 2 = 13
So, the median of the data set is: 13.
